This CL removes the JSGraph from WasmGraphBuilder and uses MachineGraph,
which is independent of the isolate, instead. In addition to using
the machine graph in the WasmGraphBuilder, this CL splits off a subclass
for compiling wrappers that does have a JSGraph and encapsulates it in
the .cc file. This makes the separation of WASM function graphs and WASM
wrapper graphs more explicit.
